STAPLE.

Specification of Letters Patent.

Application filed. May 13, 1911.

Patented. Mar. 26, 1912.

Serial No. 627,084.

To all whom 'it may concern:

Be it known that I, WARREN E. DEAN, a subject of the King of Great Britain, residing at Garmangay, in the Province of Alberta and Dominion of Canada, have invented new and useful Improvements in Staples, of which the following is a specification.

An object of the invention is to provide a staple for engagement with an article to secure other articles thereto.

For the purpose mentioned use is made of an integral piece of material having pointed ends and a head, one of the ends being longer than the other and the head being in alinement with the longer end, a port-ion adjacent the head being inclined at an angle and terminating in the shorter end and a plurality of serrations formed on the outer sides of the longer and shorter ends.

Reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which Figure 1 is a perspective view of my device. Fig. 2 is a side elevation showing my device in applied position to retain a wire in connection wit-h a post. Fig. 3 is a vertical sectional view taken on the line 3-3 in Fig. 2, looking in the direction of the arrow. Fig. 4 is a fragmentary side elevation disclosing the underlying structure of my device. Fig. 5 is a plan view of a piece of material and from which the staples are cut or stamped.

Referring more particularly to the views I provide an integral piece of material 10 from which is stamped my U-shaped staple member 10 The staple member 10 has an end 11 thereof longer than a second end 12, the said ends 11 and 12 being pointed at their outer extremities. The head 13 of the staple member 10 is preferably made flat and is disposed in longitudinal alinement with the longer end 11 as shown conveniently by the line 72-49 in Fig. 4, a portion 14 adjacent the head 13 being inclined at an angle and terminating in the shorter end 12. Formed on the outer sides of the longer and shorter ends 11 and 12 respectively are a series of serrations 15 extending such as wood or the like by subjecting the head 13 to a series of blows from a hammer or similar instrument, thus driving the staple into the wood as shown in Fig. 2, the staple being employed to retain a wire in connection with the wood. By providing the inclined portion 14, the force used to drive the staple into the wood is subjected altogether to the head 13 so that the staple member will not bend or be destroyed in-any manner when it is driven into the wood. Serrations 15 are provided to substantially hold the staple member in the wood, the said serrations being adapted to more efliciently grip the wood and retain the staple member in operative position.

As shown in Fig. 5 my staple member is preferably stamped or cut from an integral piece of material and although this is my preferred form of making the desired staple it will be understood that the staple can be quickly and easily formed by other methods.

Having thus fully described the invention, what I claim as new, is

In a device of the class described an integral piece of material bent to form a U- shaped body having one end thereof longer than the other, the said ends being pointed, a head formed at one end of the said body and in longitudinal alinement with the said longer end, an inclined portion formed adjacent the said head and terminating in the said shorter end and a series of serrations formed on the outer sides of the said head and the said longer and shorter ends of the said piece of material, the said serrations extending transversely to the said longer and shorter ends.

In testimony whereof I affix my signature in presence of two witnesses.

WARREN E. DEAN.
